Last night I was out wheeling for the second time that day. Half way through the trip I got a towel off the passenger side floor board and it was wet. I turned around and went home, but on the way my Engine light came on. No temperature problem, I checked the fluids this morning and all seem fine, maybe down a half a quart of oil.. I ran the truck to get it to leak in the cab but nothing happened but underneath water was dripping like mad. I thought maybe it was the A/C dripping. I turned off the A/C and it kept dripping. It was coming from spot on the passenger side maybe under the feet of the back passenger. Is this drip normal? Any suggestions on the Check Engine light. Maybe the heater core is bad.? Any help would be appreciated.

 

If it was plaine water it is from the A/C not the heater core, go smell it and see.
Most likely you have a plugged up A/C drain tube. Ther are 2 of them, one on either side of the transmission. Crawl under the truck with a flash light, look for a small rubber nipples that might be plugged, there will one on each side of the tranny coming thru the floor. Poke it and it will open up.
The check engine light is a separate issue and you should have someone scan the truck for codes.

Thanks Mike, Right after I posted I saw someone else with the same problem and I found the plugs and released the water.
